Phloxine B as a probe for entrapment in microcrystalline cellulose.
The photophysical behaviour of phloxine B adsorbed onto microcrystalline cellulose was evaluated by reflectance spectroscopy and laser induced time-resolved luminescence in the picosecond-nanosecond and microsecond-millisecond ranges. Analysis of the absorption spectral changes with concentration points to a small tendency of the dye to aggregate in the range of concentrations under study. Prom...
متن کاملPurified azure B as a reticulocyte stain.
A comparison has been made between reticulocyte preparations stained with purified azure B and with several commerically available batches of brilliant cresyl blue and new methylene blue. Marked variations were observed in the composition and staining performances of the various batches of the two commerically available dyes. Although there were no significant differences in reticulocyte counts...
متن کاملField evaluation of a phototoxic dye, phloxine B, against three species of fruit flies (Diptera: Tephritidae).
The xanthene dye phloxine B (D&C Red #28) bait was sprayed against fruit flies in mango orchards in 1996 and 1997. The flies used for testing were Mexican fruit fly, Anastrepha ludens (Loew), West Indian fruit fly, Anastrepha obliqua (Macquart), and Mediterranean fruit fly, Ceratitis capitata (Wiedeman). Results of the experiments indicate that the toxic efficacy of phloxine B against these fru...

متن کاملViolacein: Properties and Production of a Versatile Bacterial Pigment
Violacein-producing bacteria, with their striking purple hues, have undoubtedly piqued the curiosity of scientists since their first discovery. The bisindole violacein is formed by the condensation of two tryptophan molecules through the action of five proteins. The genes required for its production, vioABCDE, and the regulatory mechanisms employed have been studied within a small number of vio...
